Colman Patent No. 1,267,977, dated May 28, 19.18..

That patent discloses an automatic, winder come I prising a large number of winding units and a. winder-tending mechanism arranged to travel alongthe Meansis also provided for de-. tecting the fact that the cheeses being; iormed have attained the desired diameter, This means 10 consists of a feeler mounted upon the traveling winder-tending mechanism in position to gage cheeses that have been thrown out or, .i. e., placed in idle position. Whenthe ieeler engages a cheese that has reached the desired. size, devices are actuated to prevent another bobbin. from he-: ing tied to and wound on that cheese. However, since the feeler gages only throwneout cheeses, yarn continues to be wound upon the running cheeses until they are thrown out, by which time in many instances they exceed the desired size. In practice, the amount of yarn contained in the cheeses varies by as much as the quantity of yarn on one complete bobbin. This variatiQn is per? missible when the cheeses are being formed of small bobbins, but when large bobbinsare being used a. variation of one bobbinis too great to be tolerated.

The present invention aims to insure that the cheeses shall all contain approximately the same amount of yarn. In the embodiment herein shown of the invention, this object is attained by providing individual cheese measnring devices, one for each winding unit, said devices becoming effective to prevent thefurther Wind,- ing of yarn upon the cheeses as soon as the cheeses have reached a predetermineddiameter.

A contractile spring 14, together with the action of gravity, normally holds the plate '7 in the position shown in Fig. 3, the latch If) bearing against a stop portion 15 of the bracket 9, and against a portion 16 of an arm 17 whichis pivoted to the bracket 9 atl8..- Just forward of the portion 16 is an opening 191 Rigid with the arm 17 is a downwardly extending arm 26 to whichis connected one end of a yarn-breaker rod 21.

22 into proximity to the path of the ballooning yarn d that is being unwound from the bobbin a. Preferably, the lowere'nd ofthe rod 21 is to be wound,'the cheese-measuring devices are roughened as shown at 23 in Fig.6.

When the cheese has almost reached the desired diameter, its peripheryqcomes into contact with the plate '7, and as yarn continues to; be wound upon the cheese the plate 7 is swung clockwise, as viewed in Fig. 3, until the end of the, latch 10 has been moved off the portion 16 and into register with the opening lg, whereupon gravity causes the bell cr'fank 1'7, to swing clockwise, as viewed in saidfi'gure, thereby pro- 2 iecting the lower end of the rod 21 into the path ofthe ballooning yarn, thus causing the yarn to break. Thereupon the automatic throw-out mechanism hereinbefore referred to causes the cheesearm '5 to swing from the runningposition 3'6 shown at the right-hand side of Fig. 2 to, the idle position represented at the left-hand side of said figure. v v i Means is preferably provided to enable the operator to distinguish the full cheeses from thrown-out cheeses which have not quite attained the predetermined diameter. The means herein shown for this purpose comprises an indicator inthe form of a sheet-metal part 24 which 1 is mounted to slide longitudinally of the plate '7.

The lower end of the indicator 24 rests at all times upon the arm 17. When the cheese-measuring device is in its normal or reset position, as shown in Fig. 3, the upper end of the indicator 24 is invisible to the operator, but when the bell crank 17,20 moves under the action of gravity into yarn-breaking position, the indicator is lifted so that its upper end is visible above the plate 7, thussignalling to the'operator that .the cheese of that unit is to: be removed before the winderjtending mechanism reach'esit.

The yarn-breaking device 21 and the cheesemeasuring device 7 may be. reset by any preferred means. Herein I have shown the winder-tending mechanism as equipped with means to effect such resetting. Said means comprises a member'25 fixed to the framework of the vvindertending: mechanism, said member having a foam .surface26 (Fig. 5) arranged to travel'in'a path whichbrings it into engagement. with the arms 17. Upon reaching anarm' 17' 'which isin' the tripped or elevated position shown inlE'igl 4,. the cam surface 26 .depresseslsaid arm to the dotted line position represented in Fig. 3, thereby retracting the ;rod 21- and'brin'gi'ng the portion'16 ,be low thelatch 10. soon as the portion 16 has beenmoved below'the'latch 10, the" spring l4 drawsthe plate '7 against the stop 15, thus placing said..pl ate 'in..initial orlnormal position.

' diameter."

in Figs. 4 and 5, the latch lies between the plate and a web 27 struck back out of the plane of said; plate. The upper end of the latch bears against a stop lug 28 on the plate '7. An adjusting screw 29 carried by the plate '7 bears against the latch at a point below the web 27. It will be seen that by adjusting. the screw 29 the'lower'portion of the latch may be sprung a greater or less distance from the-lower end of the plate '7, thus placing the upper or cheese-gaging portion of the plate in the desired position. 30 is a stop on the bracket 9 to limit accidental rearward movement of the plate 7.

To facilitate'changes'in the size of the cheese arranged in groups, each group being mountedon a. bar 31 which is adjustably supported on the machine frame. In the present construction the bar 31 is secured to brackets 32 which are pivoted Inasmuch as ihd'v'idu'al means isprovidedfor gaging the cheeses,- it will be seen that the amount of yarn wound on each cheese core I? may be accurately controlle Q I I With the construction shown in the Colman patent above referred to, the operator has no indication of the fact that a cheese has reached the desired diameter except the fact that the cheese is thrown out immediately after the winder-tending mechanism leaves the unit Hence after the operator has replaced the full cheese with a cheese core b having a sniallaniount of starter yarn thereon the unit remains idle until the winder-tending mechanism returns to it. With the construction herein shown, wherein a'visual signal is provided, the full cheeses may it'll units in operation a greater percentage of the When small bobbinsare being unwound the breaker rods 21 may, if desired, be omitted in order to reduce the number of tailings bobbins,

and the visual signal may be used to distinguish thrown-out full cheeses from thrown-out cheeses that have not attained the predetermined While I have described the present embodiment of theinventionin considerable detail it will be understood that'the invention is notlimite'd to such details, but'that various changes may be made within the scope of the appended claims.
